+ Sumant Patro
+ Bo Yang

+3 Older Version : 00.00.03.16
+
+1. Rollback the sense info implementation
+ Sense buffer ptr data type in the ioctl path is reverted back
+ to u32 * as in previous versions of driver.
+
+2. Fixed the driver frame count.
+ When Driver sent wrong frame count to firmware. As this
+ particular command is sent to drive, FW is seeing continuous
+ chip resets and so the command will timeout.
+
+3. Add the new controller(1078DE) support to the driver
+ and Increase the max_wait to 60 from 10 in the controller
+ operational status. With this max_wait increase, driver will
+ make sure the FW will finish the pending cmd for KDUMP case.

+ * This driver handles the USB Device Controller (UDC) in Intel's PXA 27x
+ * series processors.
+ *
+ * Such controller drivers work with a gadget driver. The gadget driver
+ * returns descriptors, implements configuration and data protocols used
+ * by the host to interact with this device, and allocates endpoints to
+ * the different protocol interfaces. The controller driver virtualizes
+ * usb hardware so that the gadget drivers will be more portable.
+ *
+ * This UDC hardware wants to implement a bit too much USB protocol. The
+ * biggest issues are: that the endpoints have to be set up before the
+ * controller can be enabled (minor, and not uncommon); and each endpoint
+ * can only have one configuration, interface and alternative interface
+ * number (major, and very unusual). Once set up, these cannot be changed
+ * without a controller reset.
+ *
+ * The workaround is to setup all combinations necessary for the gadgets which
+ * will work with this driver. This is done in pxa_udc structure, statically.
+ * See pxa_udc, udc_usb_ep versus pxa_ep, and matching function find_pxa_ep.
+ * (You could modify this if needed. Some drivers have a "fifo_mode" module
+ * parameter to facilitate such changes.)
+ *
+ * The combinations have been tested with these gadgets :
+ * - zero gadget
+ * - file storage gadget
+ * - ether gadget
+ *
+ * The driver doesn't use DMA, only IO access and IRQ callbacks. No use is
+ * made of UDC's double buffering either. USB "On-The-Go" is not implemented.
+ *
+ * All the requests are handled the same way :
+ * - the drivers tries to handle the request directly to the IO
+ * - if the IO fifo is not big enough, the remaining is send/received in
+ * interrupt handling.

+ * Context : when in_interrupt() or with ep->lock held

+ * Tries to transfer all pending request data into the endpoint and/or
+ * transfer all pending data in the endpoint into usb requests.
+ * Handles states of ep0 automata.
+ *
+ * PXA27x hardware handles several standard usb control requests without
+ * driver notification. The requests fully handled by hardware are :
+ * SET_ADDRESS, SET_FEATURE, CLEAR_FEATURE, GET_CONFIGURATION, GET_INTERFACE,
+ * GET_STATUS
+ * The requests handled by hardware, but with irq notification are :
+ * SYNCH_FRAME, SET_CONFIGURATION, SET_INTERFACE
+ * The remaining standard requests really handled by handle_ep0 are :
+ * GET_DESCRIPTOR, SET_DESCRIPTOR, specific requests.
+ * Requests standardized outside of USB 2.0 chapter 9 are handled more
+ * uniformly, by gadget drivers.
+ *
+ * The control endpoint state machine is _not_ USB spec compliant, it's even
+ * hardly compliant with Intel PXA270 developers guide.
+ * The key points which inferred this state machine are :
+ * - on every setup token, bit UDCCSR0_SA is raised and held until cleared by
+ * software.
+ * - on every OUT packet received, UDCCSR0_OPC is raised and held until
+ * cleared by software.
+ * - clearing UDCCSR0_OPC always flushes ep0. If in setup stage, never do it
+ * before reading ep0.
+ * - irq can be called on a "packet complete" event (opc_irq=1), while
+ * UDCCSR0_OPC is not yet raised (delta can be as big as 100ms
+ * from experimentation).
+ * - as UDCCSR0_SA can be activated while in irq handling, and clearing
+ * UDCCSR0_OPC would flush the setup data, we almost never clear UDCCSR0_OPC
+ * => we never actually read the "status stage" packet of an IN data stage
+ * => this is not documented in Intel documentation
+ * - hardware as no idea of STATUS STAGE, it only handle SETUP STAGE and DATA
+ * STAGE. The driver add STATUS STAGE to send last zero length packet in
+ * OUT_STATUS_STAGE.
+ * - special attention was needed for IN_STATUS_STAGE. If a packet complete
+ * event is detected, we terminate the status stage without ackowledging the
+ * packet (not to risk to loose a potential SETUP packet)

+ * Endpoint definitions
+ *
+ * Once enabled, pxa endpoint configuration is freezed, and cannot change
+ * unless a reset happens or the udc is disabled.
+ * Therefore, we must define all pxa potential endpoint definitions needed for
+ * all gadget and set them up before the udc is enabled.
+ *
+ * As the architecture chosen is fully static, meaning the pxa endpoint
+ * configurations are set up once and for all, we must provide a way to match
+ * one usb endpoint (usb_ep) to several pxa endpoints. The reason is that gadget
+ * layer autoconf doesn't choose the usb_ep endpoint on (config, interface, alt)
+ * criteria, while the pxa architecture requires that.
+ *
+ * The solution is to define several pxa endpoints matching one usb_ep. Ex:
+ * - "ep1-in" matches pxa endpoint EPA (which is an IN ep at addr 1, when
+ * the udc talks on (config=3, interface=0, alt=0)
+ * - "ep1-in" matches pxa endpoint EPB (which is an IN ep at addr 1, when
+ * the udc talks on (config=3, interface=0, alt=1)
+ * - "ep1-in" matches pxa endpoint EPC (which is an IN ep at addr 1, when
+ * the udc talks on (config=2, interface=0, alt=0)
+ *
+ * We'll define the pxa endpoint by its index (EPA => idx=1, EPB => idx=2, ...)
